FUEL-BURNER.

Application filed March 3, 1913.

To all whom it may concern 7 Be it known that I, CHARLES F. PETER- soN,a citizen of the United States, residing at New York, in the county ofNew York and State of New York, have invented certain. new and usefulImprovements in Fuel- Burners, of which the following is aspecification.

This invention relates to improvements in liquid fuel burners and hasfor its object to provide a simple, efficient, and inexpensive burneradapted to provide a heater whereby heat may be diffused veryeffectively and evenly from a comparatively small combustion chamber.

A further object of my invention consists in providing, in a device ofthe kind described, improved means for stimulating the inflow of air tothe combustion chamber, and also to provide suitable passages forconveying air heated during its transit through the heater. I

With the above and other objects in view my invention consists in thecombination,

arrangement, and details of construction disclosed in the drawings andspecification and then more particular pointed out in th appendedclaims.

In the drawings, wherein similar reference characters designate similarparts throughout the respective views, Figure 1 is a vertical elevationof my heater, partly in section and broken away, showing the combustionchamber from the side, Fig. 2 is a cross-sectional elevation of myinvention with the surrounding open-ended hood removed, Fig. 8 is a topplan view of my heater with the hood removed, Fig. 4 is a fragmentaldetail view of one end of my wick-containing chamber, Fig.5 is a detailsectional view of a wick-controlling device, Fig. 6 is a transverse,fragmental sectional View of Fig. 4, Fig. 7 is a longitudinal sectionalview of Fig. 5, Fig. 8 is a bottom plan view of my heater, and Fig. 9 isan end elevation of my heater. 1

Referring to the drawings which are merely illustrative of my invention,an oil reservoir is designated 1 which is provided with a handle 2. Aplurality of substantially rectangular draft air tubes or conduits 3 aredisposed within reservoir 1 and extend above the top of said reservoir.Two of these draft tubes are shown, although if desired, the number maybe increased. Four wick-containing members 5, extend longi-Specification of Letters Patent.

tudinally in said reservoir projecting partly above and partly below thesame. Two of these members 5, it will be noticed, are on opposite sidesof each of the tubes 3, and are connected at each end and at their sidesby the substantially channel-shaped member 20, as is shown in Fig. 4.Each member 5 is hollow throughout and is formed at its upper end with areduced wick-guiding part 6. Arranged in member 5 in slidable relationis a wick-carrier 7 formed terminally with rightangular flanges 8, theupper portions 9 of which are reduced, and having racks 10formedthereon. A rod 11 passes through the member 5, one of itsextremities serving as a lug 12, which together with the oppositeprojecting portion carrying the handle disk 13 is arranged to take intoone of the slots 14 formed in the members 20 at their opposite ends,serving thereby to hold the wick containing member 5 in position inmember 20. Pinions 15 are formed upon rod 11, at suitable points,arranged to mesh with the racks 10, whereby carrier 7 may be raised andlowered; The wick carrier 7 is formed longitudinally, at spaced-apartpoints, with spring arms 16, portions of which lie flatly secured uponsaid carrier, while portions 17 curve outwardly and upwardly terminatingin angular serrated portions 18 arranged to project into the wick 19 soas to hold the same supported relatively to the carrier, said wick 19extending longitudinally of the member 5. It will be noticed that theair draft tubes 3 extend into the oil reservoir, as shown in Fig. 2. Theusual closure cap 23 is screw-threaded into the oil reservoir.

A four-sided casing 24 having supporting legs 25 is arranged to restupon the oil reservoir and it extends around the partitions and saidwick container so as to form a combustion chamber. Extending allaroundthe top edge of casing 24 is an outwardly-extending rim 26 andsaid rim, at opposite sides is formed, laterally of said member 24 witha series of longitudinallyextending ports 27. Formed longitudinally ofcasing 24 are the spaced-apart strips 27 which are V-shaped incross-section and having a series of ports 28 formed along the vertexline of each strip, each strip being disposed in alinement with the airconduits 3.

The member 24 is formed, substantially at each side of a median linewith oppositelyarranged longitudinally-extending partition interspacebetween the walls 29.

-with the rightangular handles 42.

walls 29 which are arranged to project into the space 29" between thetwo innermost wick-containing members 5, and intermediate of the walls29 is a similarly disposed plate 30 which extends some distance belowsaid walls. A deflector member 31 extends centrally and longitudinallyof casing 24 at its top and is arranged directly over the walls 29 andplate 30, said member 31 being formed with marginal flaring portions 32to conduct and deflect air over the wick-containing members 5. The rim26 of casing 24 is formed at its longitudinally-0pposite sides with thedownwardly inclined portions 33 which are bodily disposed over the outermembers 5. The openings 34 are formed upon the opposite end walls 35 and36 of member 24, and when the latter is mounted in position upon the oilreservoir, said openings 34 will communicate with the It will also benoticed that the walls 29 are formed with upwardly and outwardlyinclined portions 37. To prevent the displacement of the member 24 fromthe oil reservoir any suitable arrangement may be used, that shownembracing the rolled members 38 which are secured upon the members 20,holes being formed upon the corners of said members 24 as at 39, whichregister withthe rolled members 38 so that the removable rods 40 maypass through said holes and said rolled members and hold casing 24against vertical displacement. It will be understood that wick 19 willproject into the oil in the oil reservoir 1.

If desired the tubular member 41 may be caused to rest immediately abovethe easing 24, so that the device may be used for cooking purposes. Therods 40 are formed This member 41 will be supported upon the standard45.

W hen the wicks are lighted, and properly regulated, combustion will bestimulated by currents of air. These currents of air will be drawn inthrough the channel 29' formed between the inner wick-containing members5, or through the air conduits 3, which currents of air will be directedby the inclined portions 37 upon member 31 whose inclined portions 32will deflect the air downwardly so as to mix with the products ofcombustion emanating from the wick-containing members 5. The walls 29,plate 30, and the sides of casing 24 form relatively-largeheat-radiating surfaces, the air being heated while passing upwardlybetween the walls 29,

as said walls will radiate heat. The heated products of combustion willimpinge upon the downwardly-extending portions 37 whereby they will bedeflected against the sides of the casing 24, raising the temperature ofthe same. Unheated air may flow to the wick-containing members throughthe top open end of casing 24, down member 41. Circulation of air isvery nicely had by way of the air conduits 3, and it will be understoodthat the oil reservoir will be supported upon any suitable standard 45arranged to support the oil reservoir along its edges to cause air topass upwardly through said conduits, this air dividing in opposite pathsas it impinges against the V-shaped strips 27 so as to pass over themembers 5, part of this air making exit through the ports 28 formed uponthe strips 27. In this way the heater will not smoke and no annoyancewill be caused from the use of hydrocarbons as fuel. When the tubularmember 41 is in' use, air may pass through the ports 27 to promotecombustion.

Numerous modifications may be resorted to in practice without departingin principle from the details of construction herein disclosed.
